Two of the world’s biggest computing and data tech giants, Google and Apple, have announced within days of each other that they are now meeting all of their electricity demand with renewable energy, in one way or another.
First came Google, with a blog post on April 4 declaring that the company’s total purchase of energy from renewable sources of mainly wind and solar exceeded the amount of electricity it used across its global operations in 2017, including its offices and those energy guzzling data centres.
As the blog is careful to note, Google doesn’t claim to be 100 per cent renewable powered – “because it’s not yet possible to ‘power’ a company of our scale by 100 per cent renewable energy.”
Powering existing data centres directly with 100 per cent renewables is particularly difficult, considering that most of them are grid connected.
